Another factor influencing the friction factor is the flow regime within the pipe. Flow can generally be categorized into laminar and turbulent regimes. In laminar flow, the fluid moves in parallel layers, resulting in a lower friction factor. However, in turbulent flow, which is common in larger diameter pipes or higher velocity conditions, the friction factor increases. Suppliers should be aware of the typical applications for their galvanized iron pipes and educate their customers about maintaining flow conditions that minimize turbulence when possible.
